Abstract: G145R mutation was found in 8 patients and G145K, D144G, and D144A were also frequently found.

Method: Mutations at 10 S envelope protein positions were considered possible vaccine-escape mutations, including sP120T, sI/T126N/A, sQ129H, sM133L, sK141E, sP142S, sD144A, sG145R, sF158Y, and s PMID: 16954295

Abstract: One of them (who had been vaccinated against HBV) exhibited anti-HBs cocirculating antibodies without HBsAg escape mutants, while her unvaccinated sister showed a D144A HBsAg escape mutant without anti-HBs antibodies.

Abstract: All three patients with hepatitis B immune globulin (HBIG) treatment failure followed by nucleoside analogue treatment failure were infected with HBV genotype C; a pre-existing HBV S antigen (HBsAg) mutation (sD144A) was identified in one patient pretransplant, while sG145R mutations emerged in the other two patients post-transplant.
Localization of hepatitis B surface antigen epitopes present on variants and specifically recognised by anti-hepatitis B surface antigen monoclonal antibodies.
Abstract: A new hepatitis B virus (HBV) mutant with an Asp to Ala substitution in aa144 of the envelope major protein was identified from the blood samples of two persistently infected patients.
